Show me the work please.

A property could be sold today (year 0) to provide an after-tax cash flow from sale of $900,000. If sold next year (year 1), the property is expected to generate after-tax cash flow from operations of $25,000 and provide an after-tax cash flow of $950,000 from the sale at the end of year 1.

a. What is the marginal rate of return for holding the property for an additional year and selling at the end of year 1?_______________________
